Thats a big negatory on the noise question. Cuben is very quiet. It might look crinkly but its really not. Are you familiar with the spinnshelter? I got a used one for cheap last year and I really love the design. It is similar in shape to the SL-1 except that poles do not go inside the tarp. It has a velcro closing beak on front and a velcro door on the back end. This enables you to close it up in gnarly or cold weather, but they can be rolled up and stowed out of the way in nice weather. I am trying to install these same type of closures on my bomber tarp.

I decided on aluminized nylon for the reflective surface, tied in place. I can use the same reflective cloth panel on the inside tie-outs of my Shangri La 3. I am hoping the aluminized nylon will act as a windbreak/dew cloth/reflective surface.

Okay, here is another aspect of this:

I have had this waistbelt pack for a roll-top bag insert for kayaking.

Here it is packed "fluffy". The fact is, the Oware AsymTarp 1, Ti-Goat Bug Net Bivy, NeoAir XS stuff sacks, provided, and the Gossamer Gear PolyCro ground sheet pack so small, it would take a "fluffy" sleeping quilt to decently fill out the Sea To Summit Laundry Bag for the photo.

I haven't decided on the Sea To Summit Laundry Bag. I think the bag could be 2-4 inches taller and still be a waistbelt pack.

I decided to show "the goal". I am assembling a "10 Essentials" UL waistbelt packed outfit for walking away from the car to explore a scenic roadside landscape, with the Oware AsymTarp 1 is the shelter, if caught out in inclement weather.

Other ideas would work, as well. I am showing my idea development, here.
